Sarah Palin hasn’t formally endorsed Mitt Romney yet

While Sarah Palin has made it concretely clear that she’s opposed to President Barack Obama’s re-election, the former governor of Alaska has not yet offered a formal endorsement of the presumptive Republican nominee for president.

Palin — the 2008 Republican vice presidential nominee, who admitted to voting for Newt Gingrich during the GOP primary — said earlier this year that she would support Romney “100 percent” if he became the nominee.

But she hasn’t been very enthusiastic about supporting the former Massachusetts governor since he clinched the nod.

“I honestly believe that anybody running on a GOP ticket would be infinitely better than what we have today, with these failed socialist policies,” Palin said on NBC’s “Today” show in April — after it was clear that Romney would be the nominee.

Aides to Palin did not comment on questions posed by TheDC on this topic Monday.

It’s no surprise that she’s not Romney’s biggest fan: Fox News reported over this weekend that in giving a keynote speech to conservative activists Friday at the RightOnline convention in Las Vegas, Palin did not mention Romney once during her 35-minute address.

She has also echoed sentiments from wary conservatives, arguing during the GOP primaries that Romney needs work on his appeal to “those that are part of that Tea Party grass-roots movement.”

“It does seem that his campaign is having a tough time sort of garnering that — not just that support, but that energy that’s needed,” Palin said of Romney in February.
